Azure teams bot: how to receive files in a group chat
We have a teams bot in our organization. In a personal chat we are able to get an attachment activity with the sharepoint downloadUrl when we upload a file in the chat, but when we try to add this bot to a group and upload an image, we get an empty activity without any image data - {"contentType":"text/html","content":""}. Is it possible to upload an image in a group, and get it in our webhook as an attachment? As I read, Teams bot API only supports files in personal context, but what are the alternatives to get it in the webhook?
